컬을 업데이트/설치할 수 없습니다("다음 패키지에는 충족되지 않은 종속성이 있습니다").

curl종속성 불일치 문제로 인해 업데이트하거나 설치할 수 없습니다. (도움이 될 것 같아 제거하고 다시 설치해 보았으나 소용이 없었습니다.)

내 curl시도:

pi@RECOVERY:~ $ sudo apt-get install curl

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 curl : Depends: libcurl3 (= 7.52.1-5+deb9u1) but 7.38.0-4+deb8u5 is to be installed
E: Unable to correct problems, you have held broken packages.

그런 다음 종속성 중 하나를 시도해 보세요.

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libcurl3 : Depends: libgssapi-krb5-2 (>= 1.14+dfsg) but 1.12.1+dfsg-19+deb8u2 is to be installed
            Depends: libnghttp2-14 (>= 1.12.0) but it is not installable
            Depends: libpsl5 (>= 0.13.0) but it is not installable
            Depends: libssh2-1 (>= 1.7.0) but 1.4.3-4.1+deb8u1 is to be installed
            Depends: libssl1.0.2 (>= 1.0.2d) but it is not installable
E: Unable to correct problems, you have held broken packages.

나도 그것을 시도했지만 sudo apt-get update && sudo apt-get upgrade && sudo apt-get -f install성공하지 못했습니다. 도 아니고 sudo apt-get purge.

일부 하위 종속성(예: libnghttp2-14등 libpsl5)이 "설치할 수 없음"으로 표시됩니다. 이것이 이것과 관련이 있습니까?

이 어려움을 어떻게 극복할 수 있습니까?

- 편집하다 -

의견에서 요청한 대로 여기에 내 결과 /etc/apt/sources.list와 다음 결과가 있습니다 apt-cache policy curl.
